Re: Changing Coolant
the bottom hose on the rad is designed with push clips to allow easy release, in theory, in practice its a right pain in the arse to get the hose off because you cant push both the clips in and also apply a pulling force unless you have a triple jointed wrist. so i did what gazza suggests and disconnected the pipe at the thermostat then levered it down.
then reconnect the pipe and fill with antifreeze/water mixed 50/50. any ethylene glycol antifreeze is suitable.
the twinspark's cooling systme is self bleeding so after refilling go for a drive, then let it cool and then recheck the coolant level and top up as required.
